You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Communicate between 2 server scripts specifically, enemy spawner and timer
What is the issue? No issue, just needed idea
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
Coroutine doesn’t seem to work and Developer Hub doesn’t give me a proper idea
After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.
